It will be understood that'the handles 23 I V are farenough away from the gate so that a party desiring to open the gate may drive up with his car, andreach out and engage the handle for opening the gate. The party then drives through the drive way and stops at the handle on the opposite side of the gate; by rotating this second handle in the I opposlte direction it will cause the gate to be" moved to closed position.

In order to lock the gate against accidental opening I have provided a locking device which engages the gear 22 and prevents therotation thereof.

In order toaccomplish this; I place a beam gate.

32- in the beam 26.

A lever 33 which has a slot 34: therein is pivoted upon the bracket 35 at 36. The crank portion 29 of the shaft 28is received within, the slot 34 and capable of sliding.

movement therein. 1

A locking pawl- 37 is pivoted to the free end of the lever 33 and extends through the openings 31 and 32 directlyabove the gear 22. 9 The locking pawl 37 is designed to engage the teeth of the gear 22; and has its lower end slightly tapered so as to permit it to easily engage the teeth of the gear: 22. 7

When the locking device is in the position shown in Figure 4 of the drawings it will be impossible to rotate the gear 22, thus preventing of the opening or'closing of the In order to control the locking device when it is desired to open the gate, I have arranged arms 38 on the ends of the shaft 28. A weight 39is mounted on the ends of Y the arms 38.

When the arms 38 are swung to the position shown in dotted lines in Figure 4, then the locking pawl 37 is' out of engagement with the gear 22. Y The'gate tends to hold the locking pawl either in engagement or out of engagement with the teeth of the gear 22.

The raising and lowering of the locking pawl is accomplished by. the crank portion 29 on the shaft 28.

It will be understood that thelocking de' vice is operated just before the gate is opened and after it is closed. In this way the gate can only be opened by doing the positive act, by moving the arm 38 and the weight 39 to the position where the locking pawl will be out of engagement.

It will be seen that theparts of my device 7 are verv simple and that the gate can be easily opened and closed, and that it is very simple to lock the gate by a device controlled at a point adjacent to the handles,-

which are used for moving the gate to open or closed position. I

The advantage of the locking device can readily be seen since it insures at all times the holding of the gate in its locked position; when the locking pawl is in engagement with the gear 22 it. is impossible to move the gate, yet the parts are-so arranged that it is very easy to move the locking pawl to open position, this being accomplished by swinging the arm 38.

Some changes may be made in the con-- "struction and arrangement of the details of my device, without departing from the real spirit and purpose of my invention, and it is my intention to coverby my claim, any

modified forms of structure or use of mechanical equivalents, which may be reasonably included within their scope.

I claim as my invention: a A look for a closure having a co-operating rack and pinion, comprising a shaft designed to be above and parallel with the rotating axis of the pinion, having an upwardly inclined weighted arm, a vertical, slidable pawl, designed to be above such pinion, a slotted guide for said pawl, a lever pivotally supported betweenits ends and having one end pivoted to said pawL-a crank on said shaft having a pivotal and sliding connection with the other end of said lever,

-whereby when the weighted armis swung over centerin one direction, the pawl will be held, thereby, in engagement with the pinion, whereas when the arm is swung over center in the other direction, the pawl will be held free from the pinion. Des'Moines, Iowa, December 9, 1920.
